Capacitance
Does it ever make sense to put capacitors in series? You get less capacitance and less charge storage than with either alone. It is sometimes done in electronics practice because capacitors have maximum working voltages, and with two "600 volt maximum" capacitors in series, you can increase the working voltage to 1200 volts.

Capacitance and Charge on a Capacitors Plates
Where A is the area of the plates in square metres, m 2 with the larger the area, the more charge the capacitor can store. d is the distance or separation between the two plates.. The smaller is this distance, the higher is the ability of the plates to store charge, since the -ve charge on the -Q charged plate has a greater effect on the +Q charged plate, resulting in more electrons being ...
Why does the distance between the plates of a capacitor affect its ...
Intuitive approach: if the distance wouldn''t be a factor then you would be able to place the plates at an infinite distance apart and still have the same capacitance. That doesn''t make sense. You would expect a zero capacitance then. If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge.
